I have ticketed. with e-ticket number in receipt. Seat automatically assigned. i went in and re-assigned them, that too worked. no miles deducted after 1 week now. receipt says, I paid $10 for taxes and fare paid 0. Only concern I have is, what if at last minute, they say it is not valid ticket and you didnt pay required miles for it. shall I call US AIR or United to confirm, if all looks good? (just wait is too much at United)
